BACKGROUND: The relationship between resource utilization and postoperative length of stay (PLOS) following congenital heart disease surgery is unknown.
METHODS: We performed a retrospective cohort study using data from the Pediatric Health Information Systems database. We included subjects 1 month to 1 year of age with a PLOS of ≤ 1 month following elective, complete repair of tetralogy of Fallot (TOF) during 2004-2008 at children's hospitals that performed ≥ 10 such surgeries during the study period. We constructed three generalized linear models to assess the relationships of total costs, laboratory costs, and imaging costs during the first three postoperative days with overall PLOS. Race/ethnicity, insurance type, sex, and presence of a genetic syndrome (by ICD-9 codes) were included in the models as fixed effects; hospital of surgery was included as a random effect.
RESULTS: For 1161 eligible surgical encounters at 36 children's hospitals, mean PLOS was 7.1 days (median = 6 days). Mean total, laboratory, and imaging costs for the first three postoperative days were $26,455, $2941, and $813, respectively. Most subjects were male (58.9%), did not have a genetic syndrome (88.3%), were non-Hispanic white (58.3%), and had either public or private insurance (41.0% and 39.1%, respectively). An estimated increase in total costs of $4600 or laboratory costs of $700 in the first three postoperative days was associated with a 1-day increase in PLOS. Imaging costs were not associated with PLOS.
CONCLUSIONS: Increased resource utilization is not associated with a shorter PLOS following elective TOF repair, and it may be associated with longer PLOS.
